A large pre-dawn explosion at a warehouse in Myanmar's biggest city Yangon on Thursday killed at least 17 people and injured dozens but was not caused by a bomb, an official said.
"It was not a bomb explosion," the official said, though the cause of the blast, which sparked a large fire that destroyed many nearby storage places and homes, was still unknown.
At least 17 people, including four firefighters, had died, while 79 people were injured, including around 30 firemen, another government official told.
Residents in several areas of the city were woken by the blast around 2:00 am local time (1930 GMT), which appeared to have hit a medical warehouse in the eastern township of Mingalar Taung Nyunt, witnesses told.
Firefighters battled for hours to douse the flames and finally succeeded in extinguishing the massive fire at around 6:45am, leaving behind a scene of utter devastation.
The second government official said the blast had created a large crater and damaged several warehouses and around 50 houses in the area, most of them wooden dwellings.
